Abstract

L'invention concerne un système de filtres destiné à être utilisé avec un récipient aspirant ou un sac aspirant, le système de filtres comprenant un premier filtre et un second filtre pour retenir des particules, des aérosols de fumée, des liquides, des virus aérosolisés et des bactéries aérosolisées, tout en maintenant un flux d'air et une rétention de liquide élevés. Le premier filtre et le second filtre sont chacun multicouche pour une meilleure performance. Dans divers exemples, les premier et second filtres sont conçus pour s'intégrer directement à l'orifice de vide d'un couvercle de récipient aspirant.
